Abstract (en)
[origin: EP2341654A2] Implementations related to updating channel adaptation parameters are described. In one implementation, an R2T frame (410, 412), such as an acknowledgment (ACK) frame, is modified to carry a partial bit allocation table (BAT). The R2T frame (410, 412) may be received by a transceiver apparatus and the partial BAT carried in the header or extended header(s) of R2T frame (410, 412) may be used to update a BAT stored in the transceiver. In another implementation, a message frame (408) is modified to carry a partial BAT. The message frame (408) may be received by a transceiver apparatus and the partial BAT used to update a BAT stored in the transceiver. A unique identification number generated by the receiving transceiver apparatus may be used to synchronize BATs stored in two communicating transceivers without necessity of exchanging additional control messages.
